To appropriately determine a distance from the own vehicle to a preceding vehicle based on an image even when at least one of the own vehicle and the preceding vehicle is traveling on a curved road.SOLUTION: A preceding vehicle detection device (100) is comprised of: estimating means (11, 12) which detects a preceding vehicle traveling in front of the own vehicle based on an image obtained by imaging an object present in front of the own vehicle (1) and estimates angle information relating to an inclination of the preceding vehicle with respect to the traveling direction of the own vehicle; acquiring means (13) acquiring road information indicating a shape of a road on which the own vehicle travels; and calculation means (14) calculating distance information relating to the distance between the preceding vehicle and the own vehicle based on the angle information and the road information.SELECTED DRAWING: Figure 1
【課題】自車両及び先行車の少なくとも一方がカーブ路を走行している場合であっても、画像に基づいて自車両から先行車までの距離を適切に求める。【解決手段】先行車検出装置(100)は、自車両(1)前方を撮像した画像から、自車両の前方を走行する先行車を検出するとともに、自車両の進行方向に対する先行車の傾きに係る角度情報を推定する推定手段(11、12)と、自車両が走行している道路の形状を示す道路情報を取得する取得手段(13)と、角度情報及び道路情報に基づいて、先行車と自車両との間の距離に係る距離情報を算出する算出手段(14)と、を備える。【選択図】図1
